With reference to Fig. 3 to Fig. 6, vegetable container 100 comprises housing 110, drawer 120, floss hole 180, negative pressure portion 190 and switch valve 170.

In addition, vegetable container 100 can also comprise guiding channel 200a to 200d.

Housing 110 limits the outward appearance of vegetable container 100.Housing 110 is arranged in the storeroom F and R of refrigerator body 2.In addition, housing 110 is configured to have the dual structure of inner casing and shell.Shell can be fixed in storeroom F and R, and inner casing can be installed in shell inner casing can be extracted out from shell.

Housing 110 has the opening 113 being formed on before it.In housing 110, limit the accommodation space A that treats storing substance in order to store.

For example, housing 110 can be formed as having the shape of the rectangular parallelepiped protrusion part that is defined in the A of accommodation space wherein.More specifically, only have the front portion (opening 113) of inserting or extracting the housing 110 that passes through of drawer 120 out to be opened, and other five faces of housing 110 can be closed., in Fig. 2, at the front portion of housing 110 formation opening 113 and at layout rear surface, the rear portion of housing 110 110d.End face 110a and bottom surface 110c can be arranged in top and bottom at housing 110, and can arrange side surface 110b at the opposed sidepiece of housing 110.End face 110a and the bottom surface 110c of housing 110 can have the area larger than the side surface 110b of housing 110.

Can the negative pressure portion 190 in order to produce negative pressure (crossing vacuum) in housing 110 be installed in a side of housing 110.For example, negative pressure portion 190 can be made up of pump (vavuum pump).

In addition,, although not shown, negative pressure portion 190 can be connected to housing 110 via tube connector.Therefore,, in the time that drawer 120 inserts housing 110, negative pressure portion 190 can discharge air with to housing 110 step-downs from housing 110.

Also can be formed on the outside flange 119 extending of accommodation space A in the edge of opening 113.That is to say, flange 119 can be formed at the front of housing 110, and flange 119 is stretched out.

Flange 119 can be perpendicular to the side surface 110b of housing 110 and end face and sole arrangement.Flange 119 can refer to that perpendicular to the side surface 110b of housing 110 and end face and sole arrangement flange 119 extends in the vertical direction of housing 110 and horizontal direction.In addition, term " vertically " does not represent mathematical " completely vertical ", but represents " having the vertical of error " in engineering.

Flange 119 can be arranged perpendicular to the end face 110a of housing 110 and bottom surface 110b, to prevent because the negative pressure producing in housing 110 makes the edge of opening 113 sagging.Particularly, the bending stress that flange 119 can be formed on the vertical direction of housing 110 bending stress to produce at opening 113 edges as opposing supports.

In addition,, in the time of drawer 120 seal casinghousing 110, flange 119 provides the region contacting with drawer 120.Particularly, in the time that the inside of housing 110 is maintained at almost vacuum state, be necessary the inside of housing 110 and outside to isolate completely.Because flange 119 provides the space contacting with drawer 120, so flange 119 has improved the sealing property of vegetable container 100.In addition, use seal 140 at the contact area place between drawer 120 and housing 110, flange 119 can provide the space contacting with seal 140.

At least one surface at the edge of opening 113 can be configured to have domes, and the surperficial middle part at the edge of its split shed 113 protrudes from the outside of accommodation space A.

For example, as shown in Figure 5, the edge of opening 113 has and comprises end face 110a, the bottom surface 110c of housing 110 and the rectangular shape of side surface 110b.The end face 110a of housing 110 and bottom surface 110c are roughly longer than the side surface 110b of housing 110.Consequently, the end face 110a of housing 110 and the bottom surface 110c distortion largely due to the bending stress of the pressure differential generation between inside and the outside of housing 110.So, on the surface at the edge of opening 113 (for example, the front end of the end face 110a of housing 110) there are domes, the middle part of the edge surface of its split shed 113 protrudes from the outside situation of accommodation space A, can effectively resist the bending stress applying in housing 110 internal direction.That is to say, in the case of the edge designs of opening 113 is become to have domes, can prevent that the opening 113 of housing 110 is to housing 110 interior curve.

Housing 110 can also comprise increasing the ribs 111 of housing 110 intensity.

Ribs 111 is the elements that form on housing 110 deformation directions.Ribs 111 can be integrally formed by injection mo(u)lding and housing 110.

For example, ribs 111 can be formed on the outer surface of housing 110, with firm accommodation space A in housing 110.In addition, can form in a first direction multiple ribs 111 and can in the direction of intersecting with first direction, form multiple ribs 111.

In the inner surface 110 of housing 110, can form guide rail 117 with guiding drawer 120, make drawer 120 be inserted into housing 110 in the mode of drawer and extract out from housing 110.For example, guide rail 117 can be formed on the medial surface place of housing 110, makes guide rail 117 extend to rear portion from front portion.

The inside of drawer 120 seal casinghousings 110.Drawer 120 limits the outward appearance of vegetable container 100 together with housing 110.

For example, drawer 120 can comprise the incorporating section 123 limiting in order to receive the accommodation space for the treatment of storing substance, and is arranged in the forepiece 121 of 123 front portions, incorporating section.

Incorporating section 123 is inserted housing 110 in the mode of drawer and is extracted out from housing 110.For example, be formed on the outer surface of incorporating section 123 corresponding to the guider 129 of the guide rail 117 of housing 110, incorporating section 123 can be moved forward along guide rail 117 from housing 110 and move into backward housing 110.

For example, incorporating section 123 can have in its top and the anterior hexahedral shape of opening.

Forepiece 121 can be arranged in the front portion of incorporating section 123.Forepiece 121 can be formed has the size larger than incorporating section 123.Therefore, the EDGE CONTACT of the edge of forepiece 121 and opening 113 is with seal casinghousing 110.

Forepiece 121 can roughly form the shape of rectangle (rectangular parallelepiped protrusion part).More specifically, forepiece 121 can have the size and dimension corresponding with the size and dimension of the flange 119 of opening 113.Namely, can form forepiece 121 to contact with the flange 110 of housing 110.

In addition, forepiece 121 can be provided for the handle 125 of extracting out or inserting.

Handle 125 can be arranged on the upper area of forepiece 121.

For example, handle 125 can be recessed towards rear portion, makes to form and grasp space from the surface of forepiece 121.

In the case of the inside of housing 110 is sealed by drawer 120, between the inside of housing 110 and outside, produce pressure differential.That is to say, in the time that the inside of housing 110 is sealed by drawer 120, the inside of housing 110 is by 190 step-downs of negative pressure portion, and it is lower than the pressure of housing 110 outsides that result is that the pressure of housing 110 inside becomes.

Contact area place between the forepiece 121 of drawer 120 and the edge of opening 113 can arrange seal 140, with by the internal insulation of housing 110 in the outside of housing 110.

For example, seal 140 can be made up of elastomeric material.

Seal 140 can (or flange 119) form closed loop shape along the edge of opening 113.

Sealing holding device 160 can be set between housing 110 and drawer 120 to keep the internal insulation of housing 110 in the state of housing 110 outsides.

For example, sealing holding device 160 can comprise: holding section, is couple to one that from drawer 120 and housing 110, selects; And fastening part, be couple to another that select from drawer 120 and housing 110, make fastening part can be secured to holding section.But the present invention is not limited to this.Sealing holding device 160 can have various structures.

With reference to Fig. 5, Fig. 7 and Fig. 8, floss hole 180 is formed on the bottom surface 110c of housing 110, and the water that makes to be formed in housing 110 is collected in floss hole 180.Particularly, form floss hole 180 by the bottom surface 110c of housing 110, make the water forming in housing 110 discharge housing 110 by floss hole 180.

The position of floss hole 180 is lower than the bottom surface 110c of housing 110, and the water that makes to be formed in housing 110 can be collected in floss hole 180 due to gravity.Water in housing 110 can be when the temperature in housing 110 be reduced to dew point or when lower in housing 110 dew due to the saturated formation of humidity.

More specifically, the bottom surface 110c of housing 110 can be downward-sloping towards floss hole 180, makes mobile water because gravity can be directed effectively to floss hole 180.

The floss hole 180 of various quantity can be set.But in the situation that a floss hole 180 is set, for being conducive to the collection of water, floss hole 180 can be disposed generally on the middle part of the bottom surface 110c of housing 110.

Switch valve 170 can be set in floss hole 180 to open and close floss hole 180, to be controlled at the discharge of the water of collecting at floss hole 180 places.To be described in more detail below switch valve 170.

With reference to Fig. 5 to Figure 10, form guiding channel 200a to 200d at the inner surface place of housing 110, so that the water being formed in housing 110 is directed to floss hole 180.In addition, guiding channel 200a to 200d, for covering the dew forming at housing 110, makes to observe with the naked eye dew.

Can at least a portion of the inner surface of housing 110, form guiding channel 200a to 200d.Certainly, can on the whole inner surface of shell 110, form guiding channel 200a to 200d.

Guiding channel 200a to 200d can have various shapes.

With reference to Fig. 9 A to Fig. 9 C, can form at the inner surface place of housing 110 guiding channel 200a to 200d, make the guiding channel 200a to 200d can be recessed and outstanding so that water is guided towards floss hole 180.

For example, guiding channel 200a to 200d can comprise: towards inner outstanding at least two teats 210 of housing 110, and be arranged at least one recess 220 between corresponding teat 210, recess 220 is recessed towards the outside of housing 110.

Teat 210 extends on the left and right directions of housing 110.Repeat to be furnished with multiple teats 210 to rear portion from the front portion of housing 110.

Teat 210 is the parts that extend in one direction under outstanding more state than recess 220 at teat 210, makes the water forming in housing 110 can flow to recess 220.Between corresponding teat 210, form recess 220, make recess 220 lower than teat 210, so that water guiding channel to be provided.

Especially, with reference to Figure 10, each in teat 210 can have any shape of selecting from triangle, quadrangle and semicircle as cross sectional shape.Be that in triangle or semicircular situation, the dew forming on the inner surface of housing 110 is easy to flow to recess 220 at the cross sectional shape of each teat 210, make to observe with the naked eye dew.

More specifically, each teat 210 can be limited by the sidepiece of two inclinations 211 and 212.That is to say, each teat 210 can have triangle or the quadrangular section with two angled sides 211 and 212.

Teat 210 and recess 220 are from the front portion of housing 110 to rear portion alternative arrangement.When the temperature in housing 110 is reduced to dew point or when lower, the moisture in housing 110 can be by saturated to form dew.Dew flows to recess 220 and is stored in recess 220 from teat 210.Especially, dew does not rest on outstanding teat 210, but because the adhesive force between cohesive force and water and housing 110 inner surfaces of water moves to recessed recess 220.

In addition, when teat 210 and recess 220 from the front portion of housing 110 to the state of rear portion alternative arrangement dew be stored in recess 220 in time, the user who is arranged in the front of housing 110 cannot see the dew that is stored in recess 220 easily.That is to say, visibility is low.This is the range of vision that can hinder user because of the teat 210 that extends to right side from the left side of housing 110.

Particularly, with reference to Fig. 9 c, each teat 210 can have the leg-of-mutton shape of approximate right angle as cross sectional shape (along the line at the sensing rear portion, front portion from housing 110).

More specifically, each teat 210 can be limited by the first inclined side 211 and second inclined side 212 of extending to form summit from the opposite end of base portion 213.

Base portion 213 is any lines that interconnect contiguous recess 220.

The Length Ratio (d3:d1:d2) of base portion 213, the first inclined side 211 and the second inclined side 212 can be 1.4 to 1.6:1.9 to 2.1:2.36 to 2.64.Therefore, in the time of application Pythagorean theorem, each teat 210 can have approximate right angle triangle as cross sectional shape, and the interior angle wherein limiting between base portion 213 and the first inclined side 211 is approximately 90 degree.

Teat 210 and recess 220 are with respect to the second inclined side 212 symmetries.

Be formed as in tetragonal situation at teat 210 and recess 220, the dew forming on the inner surface of housing 110 cannot easily move to recess 220.Therefore, dew may rest on teat 210, and consequently, user can observe dew.

Be formed as in leg-of-mutton situation at teat 210 and recess 220, the dew being formed on the inner surface of housing 110 can move to recess 220 easily.Particularly, being formed on dew on the inner surface of housing 110, on the inner surface of housing 110, between the first inclined side 211 and the second inclined side 212, to have large contact surface long-pending.The long-pending adhesive force that increases dew of such large contact surface.Consequently, dew can move to recess 220 easily.

Particularly, in the situation that teat 210 and recess 220 are formed as right angled triangle, the dew being formed on the inner surface of housing 110 can more easily move to recess 220.Specifically, in the case of the interior angle (angle between the first inclined side 211 and the second inclined side 212) of each recess 220 become large, the dew that is formed on the summit place of teat 210 cannot easily move to recess 220.On the other hand, in the case of the interior angle (angle between the first inclined side 211 and the second inclined side 212) of each recess 220 excessively reduces, the excessive height of each teat 210 increases, and consequently the thickness of the strength decreased of housing 110 and housing 110 increases.

Therefore, in the situation that teat 210 and recess 220 are formed as right angled triangle, are necessary to configure teat 210 and recess 220 and make the interior angle (angle between the first inclined side 211 and the second inclined side 212) of each recess 220 reduce the height of each teat 210 simultaneously can excessively not increase the adhesive force between water and recess 220.

The first inclined side 211 of each teat 210 can be positioned at the more position by housing 110 front portions than the second inclined side 212 of each teat 210.

The summit of the each teat 210 being formed by the first inclined side 211 and the second inclined side 212 can be round, with the dew that prevents from forming at the summit place of each teat 210 because gravity falls into housing 110 and is directed to recess 220 with the dew that the summit place at each teat 210 is formed.

Spacing P between corresponding teat 210 can be 1.5mm to 2.5mm.Spacing P between corresponding teat 210 is greater than 2.5mm, and the dew being formed on the inner surface of housing 110 can not easily move to recess 220.On the other hand, the spacing P between corresponding teat 210 is less than 1.5mm, and each recess 220 can not provide enough spaces to collect dew, causes and can observe with the naked eye dew.

In addition, each teat 210 can have the height of 1.5mm to 2.5mm.In the case of the height of each teat 210 is excessive, the strength decreased of housing 110.On the other hand, in the case of the height of each teat 210 is too little, each recess 220 can not provide enough spaces to collect dew.

A position of the bottom surface 110c of water collection unit 181 in can recessed housing 110 is to be collected in water in housing 110.Water collection unit 181 is formed in water in housing 110 along the mobile parts of the inner surface of housing 110, makes water be collected in water collection unit 181 places.

Discharge portion 182 allows water collection unit 181 to be communicated with the outside of housing 110, makes the water of collecting at water collection unit 181 places can discharge housing 110.Discharge portion 182 can have the width less than water collection unit 181.Width refers to the length of left and right directions in Figure 16.In addition, discharge portion 182 can have the size less than water collection unit 181 or internal diameter.

More specifically, water collection unit 181 and discharge portion 182 can respectively be formed as the shape in hole.Water collection unit 181 and discharge portion 182 can have identical central shaft.The external diameter of water collection unit 181 can be greater than the external diameter of discharge portion 182.That is to say, water collection unit 181 can be recessed in a position of the bottom surface of housing 110 110c, and discharge portion 182 can, through the bottom surface formation of water collection unit 181, make discharge portion 182 be communicated with the outside of housing 110.

The internal diameter of water collection unit 18 or width can be uniformities.Alternately, water collection unit 181 can have end difference, is stuck by the engaging protrusion (will be described below) of this end difference fixed part.

For example, discharge portion 182 can be the through hole forming through the bottom of water collection unit 181.

In the present embodiment, switch valve 1700 is arranged in floss hole 180 to open and close floss hole 180.Can be by the pressure differential closing switch valve 1700 between the inside of housing 110 and outside, and in the time that the pressure differential between inside and the outside of housing 110 is released, open switch valve 1700.The material that switch valve 1700 can be out of shape by the pressure differential between inside and outside by housing 110 is made.For example, switch valve 1700 can be made with flexible rubber or silicones by being ductile.

For example, switch valve 1700 can comprise fixed part 1710 and close contact lip sheet 1750.

Fixed part 1710 have be limited to wherein space, discharge water by this space.Fixed part 1710 is inserted and secured in floss hole 180.That is to say, fixed part 1710 can have the external shape corresponding to the interior shape of floss hole 180.The space of the draining of fixed part 1710 can have various shapes.Fixed part 1710 can be fixed in floss hole 180.

For example, in the situation that floss hole 180 has cylindrical shape, the external shape of fixed part 1710 can be the cylindrical shape corresponding to the internal diameter of floss hole 180.In addition, in fixed part 1710, limit drainage space.

Fixed part 1710 can comprise and be discharged mouthful 180 engaging protrusion of blocking 1720, and is connected to the distance holding member 1730 of two close contact lip sheets 1750, in order to keep the distance between close contact lip sheet 1750.

Switch valve 1700 is discharged mouth 180 by engaging protrusion 1720 and blocks.Because switch valve 1700 and housing 110 separate manufacture, be then inserted into the floss hole 180 being formed in housing 110, so need fixture in the time that switch valve 1700 is inserted to floss hole 180.The end difference that engaging protrusion 1720 is formed in floss hole 180 blocks that switch valve 1700 is fixed in floss hole 180.

For example, can have at least two inclined plane 1730a and 1730b apart from holding member 1730, the distance between them reduces to close contact lip sheet 1750 gradually from engaging protrusion 1720.That is to say can there is at least two inclined plane 1730a and 1730b apart from holding member 1730, make to be formed as having apart from holding member 1730 funnel shaped that is limited to the guiding channel of water wherein.

That is to say to have at least two inclined plane 1730a and 1730b apart from holding member 1730, the distance between them reduces to the outside of housing 110 gradually from the inside of housing 110.

In the time that drawer 120 is closed, under the low vacuum state of the pressure that the inside of housing 110 is maintained at housing 110 inside lower than housing 110 external pressures.On the other hand, in the time that drawer 120 is opened, the pressure of housing 110 inside becomes the atmospheric pressure equating with housing 110 external pressures.Therefore, there is at least two the inclined plane 1730a and the 1730b that show uniform rigidity apart from holding member 1730, and the distance between them reduces to the outside of housing 110 gradually from the inside of housing 110, due to the close contact lip sheet 1750 of the state compared with large pressure reduction and in close contact between the inside of housing 110 and the outside of housing 110, in the time that closing, drawer 120 is opened preventing.

Two inclined plane 1730a and 1730b make to be limited to apart from the shape of the water guiding channel in holding member 1730 and are deformed into the slit-shaped (referring to Figure 16 and Figure 12) of observing from top.That is to say, be adjacent to distance between two inclined plane 1730a and the 1730b of close contact lip sheet 1750 less, and width between inclined plane 1730a and the front and rear of 1730b is relatively larger than the distance between two inclined plane 1730a and 1730b.Therefore, be limited to apart from the shape of the water guiding channel in holding member 1730 and become the slit-shaped with long narrow gap.

When being limited to while becoming slit-shaped apart from the shape of the water guiding channel in holding member 1730 due to two inclined plane 1730a and 1730b, two close contact lip sheets 1750 that are couple to the lower end of inclined plane 1730a and 1730b are spaced apart from each other with the state that limits long narrow gap between close contact lip sheet 1750.Therefore,, in the time producing pressure reduction between housing 110 inside and outside, two close contact lip sheets 1750 are easy to contact with each other, and consequently can guarantee larger contact area.That is to say, be eachly formed as two tabular close contact lip sheets 1750, can be to provide the state of narrow slit to be spaced apart from each other by two inclined plane 1730a and 1730b between close contact lip sheet 1750.

Meanwhile, in the case of the passage apart from limiting in holding member 1730 is too wide, due to the pressure differential of housing 110 between inside and outside, may be difficult to obtain the contact between close contact lip sheet 1750, consequently extraneous air may be introduced into housing 110.On the other hand, in the case of the passage apart from limiting in holding member 1730 is too narrow, cannot easily the water in housing 110 be discharged to outside.Owing to being limited to apart from the passage in holding member 1730 because two inclined plane 1730a and 1730b have long narrow slit-shaped, so the space of enough draining can be provided in housing 110, improve the contact force between close contact lip sheet 1750 simultaneously.

Consider the keep at a distance weight of parts 1730 and close contact lip sheet 1750 of low vacuum pressure in housing 110 and distance, set the distance between two inclined plane 1730a and the 1730b that is adjacent to close contact lip sheet 1750.That is to say, the distance between two inclined plane 1730a and 1730b bottom is set to the space of the draining that provides enough in housing 110, increases the contact force between close contact lip sheet 1750 simultaneously.

Close contact lip sheet 1750 is connected to the bottom of fixed part 1710, makes the close contact lip sheet 1750 can be because the pressure differential between the inside of housing 110 and outside contacts with each other.
